Description

Technical Field

[0001] The invention relates to the technical field of noise reduction motors, in particular to a noise reduction motor and a noise reduction method for a washing machine motor. Background Art

[0002] Motor noise mainly comes from three aspects, namely air noise, mechanical noise and electromagnetic noise, but sometimes internal circuit noise is also listed as one of the noise sources.

[0003] As for mechanical noise, when the motor is working, some vibrations will be transmitted through the housing, components, working surface, etc., generating noise. Poor dynamic balance of the rotor and excessive friction of the shaft bearing are also the main causes of noise.

[0004] Therefore, reducing motor vibration is one of the effective methods to reduce noise. Existing shock absorption usually involves adding some vibration-damping materials around or inside the motor, or performing shock-absorbing treatment on the motor through a shock-absorbing structure. However, this method can only provide shock absorption in a single direction, and is unable to automatically lubricate the bearings according to the shock absorption intensity, resulting in poor noise reduction effect.

[0018] As a further solution of the present invention: the pumping mechanism includes a piston cylinder fixedly mounted on the support seat, a delivery pipe and a guide pipe are fixed on the piston cylinder, the delivery pipe is connected to the storage box, the guide pipe passes through the connecting seat and is connected to the motor body, and a driven component connected to the guide column is arranged in the piston cylinder.

[0019] As a further solution of the present invention: the driven assembly includes a piston disk slidably mounted on the piston cylinder, a push rod penetrating the piston cylinder is fixed on the piston disk, a connecting plate is fixed to the end of the push rod facing away from the piston disk, and a connecting rod hinged to the guide column is hinged on the connecting plate.

[0020] A noise reduction method for a washing machine motor comprises the following steps:

[0021] Step 1: The support base can be fixed in the washing machine, and the connecting base can be installed in the washing machine through the support assembly control;

[0022] Step 2: When the motor body controls the output shaft to rotate, the vibration of the motor body will be transmitted to the support assembly through the connecting seat;

[0023] Step 3: The support assembly will drive the vertical shock absorbing mechanism to move, and under the action of the vertical shock absorbing mechanism, provide vertical support force to the connecting seat. At the same time, the vertical shock absorbing mechanism will also drive the lateral shock absorbing assembly to move, so as to provide support force in the horizontal direction of the connecting seat;

[0026] When the motor body is working, the vibration force it generates will be transmitted to the support assembly through the connecting seat. Under the action of the support assembly, the vertical shock absorbing mechanism and the lateral shock absorbing assembly will be driven to move, so as to apply horizontal and vertical shock absorbing forces to the motor body, thereby achieving the purpose of reducing the noise of the motor body.

[0027] If the bearing friction of the output shaft is too large, the vibration force generated by the motor body will increase, and the noise will also increase. At this time, the connecting seat controls the movement stroke of the vertical shock absorbing mechanism to increase, thereby increasing the vertical supporting force.

[0028] At the same time, under the action of the lateral shock absorbing component, the pumping mechanism moves to transport the lubricating oil in the storage box to the bearing, thereby further reducing the noise generated by the motor and adjusting the lubrication level in real time according to the vibration conditions when the motor is running; through the dual effects of shock absorption and lubrication, the effect of real-time noise reduction is achieved when the motor is working. At the same time, the bearings can be fully lubricated in time to prevent the bearings from being damaged due to excessive wear due to insufficient lubrication.

[0029] The present invention combines longitudinal shock absorption and lateral shock absorption for vibration protection, and cushions vibration under the premise of ensuring sufficient support; it can not only reduce the noise generated during operation, but also ensure that the connection is stable and not loose; at the same time, the cooperation of the set pumping mechanism and the shock absorbing component is utilized to achieve lubrication compensation, further reducing the negative impact caused by wear and noise.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0043] See also Figure 1-Figure 10 In an embodiment of the present invention, a noise reduction motor includes: a connecting seat 1, a motor body 2, an output shaft 3, a supporting seat 4, a supporting assembly, a vertical shock absorbing mechanism, a lateral shock absorbing assembly, a material storage box 18, and a pumping mechanism. When the motor is in use, the noise generated by the motor is usually caused by vibration. In order to prevent the motor body 2 from generating excessive noise due to excessive vibration frequency when the motor body 2 is working, it is necessary to perform shock absorbing treatment on the motor body 2. Therefore, when the motor body 2 is working, the vibration force generated by the motor body 2 will be transmitted to the supporting assembly through the connecting seat 1. Under the action of the supporting assembly, the vertical shock absorbing mechanism and The lateral shock absorbing assembly moves to apply horizontal and vertical shock absorbing forces to the motor body 2, thereby achieving the purpose of reducing the noise of the motor body 2. If the bearing friction of the output shaft 3 is too large, the vibration force generated by the motor body 2 increases. Therefore, under the action of the lateral shock absorbing assembly, the pumping mechanism moves to transport the lubricating oil in the storage box 18 to the bearing, thereby further reducing the noise generated by the motor. Through the dual effects of shock absorption and lubrication, the effect of real-time noise reduction is achieved when the motor is working. At the same time, the bearings can also be lubricated in time to prevent the bearings from being damaged due to insufficient lubrication.

[0044] The details are as follows, including:

[0045] A connecting seat 1, and a motor body 2 fixedly mounted on the connecting seat 1, wherein the motor body 2 is connected to an output shaft 3;

[0046] Among them, in the use of existing household appliances, noise control occupies a pivotal position. In particular, motor noise is a key indicator for evaluating the quality of motor products. Motor noise mainly comes from three aspects, namely air noise, mechanical noise and electromagnetic noise, but sometimes the internal noise of the circuit is also included as one of the noise sources. As for mechanical noise, when the motor is working, some vibrations generated will be transmitted through the casing, components, working surfaces, etc., generating noise. Therefore, reducing motor vibration is one of the effective ways to reduce noise. At the same time, as the motor works, the bearing wear of its shaft will increase, and the lubricating oil in the bearing will gradually decrease with the increase of working time. The wear of the bearing will also increase the noise generated when the motor is working. Therefore, timely lubrication of the bearing is also one of the effective ways to reduce motor noise.

[0047] Also includes:

[0048] See also Figure 1-Figure 6 , support seat 4, the support seat 4 is connected to the connecting seat 1 through a support assembly, the support assembly includes a plurality of support sleeves 5 rotatably mounted on the support seat 4 and equidistantly distributed around the circumference, a support rod 6 is slidably mounted in the support sleeve 5, and the support rod 6 is fixedly connected to the connecting seat 1.

[0049] In detail, when the washing machine is in use, the motor is required to be used as an output source, so the motor needs to be installed in the washing machine. At this time, the support base 4 can be fixedly installed in the washing machine by bolts. At the same time, under the action of the support sleeve 5 and the support rod 6, the motor body 2 is controlled to be located in the washing machine through the connecting base 1. In the initial state, under the action of the vertical shock absorbing mechanism, the support rod 6 is located at the end of the stroke away from the support sleeve 5, so that the distance between the connecting base 1 and the support base 4 is the largest. When the washing machine needs to be used, the motor body 2 works and controls the output shaft 3 to rotate. If the rotor in the motor body 2 is not well balanced, or the bearing generates friction vibration due to excessive rotation speed, the motor body 2 will generate vibration, which is then transmitted to the connecting base 1. Under the action of the connecting base 1, the support rod 6 is controlled to move toward the direction of the support sleeve 5 to apply a force to the vertical shock absorbing mechanism. At the same time, under the action of the vertical shock absorbing mechanism, the support rod 6 is controlled to be reset again, thereby performing shock absorbing treatment on the motor body 2 to reduce the noise generated by the vibration of the motor body 2.

[0050] See also Figure 1-Figure 6, the support assembly is connected with a vertical shock absorbing mechanism, and the vertical shock absorbing mechanism is a plurality of groups. The support assembly can apply a vertical support force to the connecting seat 1 through the vertical shock absorbing mechanism. The vertical shock absorbing mechanism includes a rotating ring 13 fixedly mounted on the support sleeve 5, and a lower annular guide rail 1301, an inclined guide rail 1302, and an upper annular guide rail 1303 are fixed on the rotating ring 13. The lower annular guide rail 1301 is connected to the inclined guide rail 1302 and the upper annular guide rail 1303; wherein, there is a drop between the upper annular guide rail 1303 and the lower annular guide rail 1301, and they are connected through the inclined guide rail 1302; elastic components are provided on the support sleeve 5 and the support rod 6, wherein, The elastic component includes a movable ring 10 rotatably mounted on the support sleeve 5, and a protruding block 12 is fixed on the movable ring 10. The protruding block 12 can slide along the lower annular guide rail 1301, the inclined guide rail 1302, and the upper annular guide rail 1303. A first spring 11 is sleeved on the support sleeve 5 and the support rod 6, and the first spring 11 abuts against the movable ring 10. A guiding structure connected to the support rod 6 is provided on the support sleeve 5. The above-mentioned guiding structure includes a groove structure opened on the support rod 6, and the groove structure includes a vertical groove 7 and a spiral groove 8. A limiting block 9 is fixed on the inner wall of the support sleeve 5, and the limiting block 9 can slide along the vertical groove 7 and the spiral groove 8.

[0051] It should be noted that the end of the vertical groove 7 away from the rotating ring 13 is connected to the end of the spiral groove 8 close to the rotating ring 13. Specifically, the vertical groove 7 extends toward the rotating ring 13 on the outer wall of the support rod 6 parallel to the axis of the support rod 6, and the end of the vertical groove 7 away from the rotating ring 13 and the end of the spiral groove 8 close to the rotating ring 13 have a smooth transition, and the groove width and groove depth of the vertical groove 7 are consistent with those of the spiral groove 8; in the initial state, the first spring 11 is in a compressed state, so that the movable ring 10 is located at the end of the stroke away from the connecting seat 1, the limit block 9 is located at the end of the stroke of the vertical groove 7 away from the spiral groove 8, and the protruding block 12 is located at the connection position between the lower annular guide rail 1301 and the inclined guide rail 1302. When the motor body 2 is working, the vibration force generated will be transmitted to the support rod 6 through the connecting seat 1, thereby controlling the support rod 6 to move toward the support sleeve 5. At this time, the first spring 11 will be compressed, and the support rod 6 will also drive the vertical groove 7 and the spiral groove 8 to move, so that the limit block 9 moves along the length direction of the vertical groove 7. Under the action of the limit block 9 and the vertical groove 7, it is ensured that the support sleeve 5 will not rotate to ensure that the rotating ring 13 will not rotate. Therefore, the movable ring 10 will not move. When the supporting force provided by the first spring 11 to the connecting seat 1 is equivalent to the vibration force received by the connecting seat 1, at this time, the first spring 11 is elastically released and drives the support rod 6 to move toward the initial position. The above steps are repeated to provide a vertical shock absorbing effect for the motor body 2.

[0052] Preferably, if the bearing lubrication effect on the output shaft 3 is not good, or the friction generated by other structures in the motor body 2 increases, the vibration force generated by the motor body 2 will increase. Therefore, the travel of the support rod 6 toward the support sleeve 5 increases. When the limit block 9 disengages from the vertical groove 7 and enters the spiral groove 8, the support sleeve 5 will rotate and drive the rotating ring 13 to rotate, thereby controlling the inclined guide rail 1302 to contact the protruding block 12. Under the action of the inclined guide rail 1302 and the protruding block 12, the movable ring 10 moves toward the connecting seat 1, so as to synchronously apply pressure to the two ends of the first spring 11 through the movable ring 10 and the connecting seat 1, thereby further increasing the supporting force on the connecting seat 1 to reduce the vibration frequency of the motor body 2.

[0053] See also Figure 1 , Figure 2 , Figure 4 , Figure 7The lateral shock absorbing components also consist of multiple groups, which are arranged on the connecting seat 1 and connected to the vertical shock absorbing mechanism, and are used to provide horizontal support force for the connecting seat 1. The lateral shock absorbing components include a guide column 14 fixedly mounted on the movable ring 10, and a guide ring 15 symmetrically arranged is slidably mounted on the guide column 14. A hinged rod 17 hinged to the connecting seat 1 is hinged on the guide ring 15, and a second spring 16 abutting against the guide ring 15 is sleeved on the guide column 14.

[0054] Specifically, the hinged rod 17 includes a rod body part and a hinge seat part, one end of the rod body part is hinged to the guide ring 15 through a pin shaft, and the other end of the rod body part is hinged to the hinge seat part through another pin shaft, and the hinge seat is fixed to the connecting seat 1.

[0055] Furthermore, since the motor body 2 will also generate horizontal vibrations when in use, it is necessary to provide horizontal support force for the motor body 2. In the initial state, the second spring 16 is in a compressed state, so that the distance between the two guide rings 15 is maximized to control the angle between the hinge rod 17 and the guide column 14 to be maximized. When the motor body 2 is working, the vibration force generated will be transmitted to the support rod 6 through the connecting seat 1, so that the support rod 6 moves toward the support sleeve 5, and the distance between the connecting seat 1 and the support seat 4 is reduced. The connecting seat 1 will also drive the hinge rod 17 to move to control the two guide rings 15 to be maximized. The rings 15 move in the direction of approaching each other, and at the same time, the guide ring 15 will also compress the second spring 16 to provide horizontal support force to the connecting seat 1 through the hinge rod 17. Since there are four groups of guide columns 14, and the four guide columns 14 are combined to form a positive direction shape, when the motor generates disordered vibrations, the cooperation of the guide ring 15 and the second spring 16 can provide support forces in multiple horizontal directions to the motor. At the same time, the guide ring 15 and the second spring 16 can also provide support force in the vertical direction to the connecting seat 1, so as to further reduce the vibration generated when the motor is working and ensure better noise reduction effect.

[0056] Preferably, if the vibration force generated by the motor body 2 is too large, under the action of the protruding block 12 and the inclined guide rail 1302, the movable ring 10 moves in a direction away from the support seat 4 to control the movement of the guide column 14. Under the action of the hinge rod 17, the compression amount of the second spring 16 is further increased to further increase the support force of the connecting seat 1 in the horizontal direction.

[0057] See also Figure 2 , Figure 8 , Fig. 9, a storage box 18 is fixedly mounted on the support seat 4, and a pumping mechanism connected to the storage box 18 and the lateral shock absorbing assembly is provided on the support seat 4, and the pumping mechanism can transport the lubricating oil in the storage box 18 to the motor body 2 when the vertical shock absorbing mechanism moves, and the pumping mechanism includes a piston cylinder 19 fixedly mounted on the support seat 4, and a delivery pipe 24 and a guide pipe 25 are fixed on the piston cylinder 19, and the delivery pipe 24 is connected with the storage box 18, and the guide pipe 25 passes through the connecting seat 1 and is connected to the motor body 2, and a driven assembly connected to the guide column 14 is provided in the piston cylinder 19, wherein the driven assembly includes a piston disk 20 slidably mounted on the piston cylinder 19, and a push rod 21 passing through the piston cylinder 19 is fixed on the piston disk 20, and a connecting plate 22 is fixed on the end of the push rod 21 away from the piston disk 20, and a connecting rod 23 hinged to the guide column 14 is hinged on the connecting plate 22.

[0058] Furthermore, the storage box 18 is filled with lubricating oil. If the vibration force generated by the motor body 2 is too large, it is most likely caused by the low lubrication of the bearing. Therefore, it is necessary to add lubricating oil to the bearing of the output shaft 3. Two one-way valves are installed on the piston cylinder 19, and the two one-way valves are respectively connected to the delivery pipe 24 and the guide pipe 25. In the initial state, the guide column 14 is located at the end of the stroke toward the support seat 4. Under the action of the connecting rod 23, the connecting plate 22 is located at the end of the stroke toward the support seat 4, so that the piston disc 20 is controlled by the push rod 21 to be located at the end of the stroke in the piston cylinder 19. Under the action of the piston disc 20, the lubricating oil in the storage box 18 is sucked into the piston cylinder 19 through the delivery pipe 24. If the vibration force generated by the motor body 2 is too large, under the action of the protruding block 12 and the inclined guide rail 1302 , so that the movable ring 10 moves in the direction away from the support seat 4, and the movable ring 10 will also drive the guide column 14 to move, so as to control the connection plate 22 to move in the direction away from the support seat 4 through the connecting rod 23. The connecting rod 23 will also control the movement of the push rod 21 through the connecting plate 22 to control the piston disc 20 to move in the direction away from the support seat 4. Under the action of the piston disc 20, the lubricating oil in the piston cylinder 19 is transported to the motor body 2 through the guide pipe 25, and then transported to the rotating shaft of the output shaft 3. When the guide column 14 returns to the initial position, the piston disc 20 is controlled to move toward the initial position, so as to suck the lubricating oil in the storage box 18 into the piston cylinder 19 through the delivery pipe 24, and repeat the above steps, so as to realize the effect of automatically detecting the lubrication and wear of the bearing according to the vibration intensity of the motor body 2, and automatically delivering lubricating oil to the bearing.

[0059] Preferably, the present application can provide lateral and vertical support forces to the motor by conducting the vibration force of the motor, and can detect the lubrication of the bearing according to the vibration amplitude, and add lubricating oil to the bearing in time, and through the dual effects of shock absorption and lubrication, the effect of real-time noise reduction can be achieved when the motor is working. At the same time, by lubricating the bearings, the problem of bearing damage due to insufficient lubrication can be prevented.

[0060] A noise reduction method for a washing machine motor comprises the following steps:

[0061] Step 1: The support base 4 can be fixed in the washing machine, and the connecting base 1 can be installed in the washing machine through the support assembly;

[0062] Step 2: When the motor body 2 controls the output shaft 3 to rotate, the vibration of the motor body 2 will be transmitted to the support assembly through the connecting seat 1;

[0063] Step 3: The support assembly will drive the vertical shock absorbing mechanism to move, and under the action of the vertical shock absorbing mechanism, provide vertical support force to the connecting seat 1. At the same time, the vertical shock absorbing mechanism will also drive the lateral shock absorbing assembly to move, so as to provide support force in the horizontal direction of the connecting seat 1;

[0064] Step 4: If the vibration force generated by the motor body 2 is too large, the pumping mechanism moves under the action of the lateral shock absorbing assembly. Under the action of the pumping mechanism, the lubricating oil in the storage box 18 is transported to the motor body 2 to lubricate the bearings of the output shaft 3.
